In fact, many "old antiques" have already laid a curse when they were young. Therefore, although most patients with Alzheimer's disease are over 60 years old, prevention should start at the age of 35, such as limiting alcohol and quitting smoking, adjusting diet, regular physical examination, and persisting in exercise.

1. Do regular brain health check-ups to find brain lesions as soon as possible.

Brain examination is the most intuitive basis for diagnosing Alzheimer's Harmo's disease. Regular brain health examination is an effective way to ensure the timely detection of brain lesions. Brain examination mainly includes EEG, brain CT scan or MRI (nuclear magnetic resonance).

Symptoms that can be detected by EEG: nonspecific diffuse slow wave can be seen, the rhythm of α wave slows down and the amplitude becomes lower; In severe cases, sharp waves of 0.5c/s can be released synchronously on both sides.

The rheoencephalogram showed that the regional cerebral blood flow in cerebral cortex decreased and the cerebral oxygen metabolism rate decreased. Brain CT scans often show different degrees of ventricular enlargement, cortical atrophy and sulcus widening.

Some people may think that they are in their prime and strong, and diseases like Alzheimer's disease are far away from them. In fact, this disease often lurks in young people, and after a long incubation period, it will occur in old age, when irreversible changes have taken place in the brain.

2. Prevent lifestyle diseases such as diabetes, hypertension and obesity.

Improving living habits is the key.

The occurrence of Alzheimer's disease is closely related to bad living habits, and a set of healthy living habits includes all aspects of diet and daily life, which can balance the needs of life and work and effectively prevent the occurrence and progress of Alzheimer's disease.

The following are some lifestyle habits that are beneficial to prevent Alzheimer's disease for your reference.

Sometimes you are alive and get enough sleep.

A study shows that getting enough sleep for 8 hours every night can effectively prevent the occurrence of Alzheimer's disease. However, with the growth of age, people's sleep time is also decreasing, and the quality of sleep becomes worse and worse after entering old age. But keep at least 6 hours of sleep every day and arrange lunch break at noon.

Do more exercises

Old people are not suitable for strenuous exercise, but there is nothing they can do. Choosing some moderate exercise, such as walking and Tai Ji Chuan, can not only strengthen the body, but also prevent Alzheimer's disease. At the same time, walking helps to calm the mood and improve short-term memory. You can spend 1 hour walking and shopping every day.

More exposure to nature is good for brain health. No matter in winter or summer, the effect of walking is equally good.

Often bask in the sun

Sunlight can promote nerve growth factor, like "long hair", and make nerve fibers grow. Receiving sunshine every day, at least it is not easy to be depressed.

Protect eyesight

Maintaining good eyesight can reduce the risk of Alzheimer's disease by 63%. The visual reaction of the eyes to the outside world will affect the brain function, especially for the elderly. The old man's eyesight is poor, so he should seek medical treatment in time.

Keep a diary.

The first way to stimulate the vitality of the human brain is to keep a diary and record what happened two days ago. The organ responsible for brain memory will reorganize the forgotten things, so that the brain can get effective exercise, thus preventing Alzheimer's disease.

4. Exercise your brain in your daily life

Most patients with Alzheimer's disease are caused by the gradual decline of brain function. The decline of brain function in the elderly is not only caused by the natural aging of the brain itself, but also caused by long-term non-use of the brain.

Clinical research shows that long-term exercise of brain function in the elderly is the best way to delay brain aging. For example, regular digital exercises and listening to music can effectively relieve the symptoms of Alzheimer's disease.

Especially when the elderly have memory loss, no sense of direction in time and place, and the ability to understand or arrange affairs reasonably declines, more attention should be paid to brain exercise.

Distinguish coins with your fingers

Keep several coins of different denominations in your pocket at any time, and try to distinguish them with your fingertips when you are free. This can stimulate the cerebral cortex and tap some hidden abilities of the brain.

Hold your nose and drink coffee or tea.

The aroma of coffee and tea will be introduced into the brain through the nasal mucosa and olfactory nerve, and then analyzed in the brain. But now that we can't smell the fragrance, the brain can only rely on the taste of the tongue to desperately analyze what enters the mouth, so that the brain function can be exercised.

Slap the scalp

There is a rich vascular network on the scalp. Moderate slapping on the scalp can improve the blood circulation of the scalp and improve the intracranial circulation. When combing your hair every day, gently hit the hairline in front of your head with the barbed side of the comb. The strength of the blow depends on your tolerance, and a slight scalp pain is appropriate. Every morning and evening 1 time, 5 minutes each time. In addition, you can also rub the scalp with your fingers to stimulate intracranial blood circulation.

Movable finger

There are many peripheral nerves in the hand, especially the fingertip. Moving fingers can directly stimulate brain cells and prevent and delay the degeneration of brain cells. There are many ways to move your fingers, such as holding the cup with both hands and turning it back and forth in your hands, or turning pecans and tethers when drinking water. In addition, you can usually do more finger movements to enhance the stimulation of the brain.

Rotating tongue

The lingual nerve is connected with the brain. Frequent tongue rotation can indirectly stimulate the left brain. After brushing your teeth every morning, rotate your tongue in your mouth for 5 times, then open your mouth, gently stick out your tongue for 2 ~ 3 seconds, and practice for 5 times repeatedly, or rub the fingertips of your right index finger, middle finger and ring finger from the bottom of your left ear to your throat for 30 times.

5. Re-recognize the wonderful meaning of balanced diet and nutrition.

Balanced nutrition, pay attention to balance. Preparing a balanced diet is to choose a variety of foods, so that the nutrients contained are complete and the proportion is appropriate to meet the needs of the human body.

That is, the nutrition is balanced, the calorie ratio of protein, fat and sugar is 1: 2.5: 4, high-quality protein accounts for 1/2 ~ 2/3 of the total amount of protein, and animal protein accounts for1/3; The balance between staple food and non-staple food, it is unhealthy to eat non-staple food only for fitness; Cold and heat balance, that is, the collocation of cold food and hot food; The balance between hunger and satiety, nutrition experts specially suggested: "If you eat more meals a day, you will not have enough food. Eat when you are hungry and eat very little. "

The following diet helps prevent memory loss and Alzheimer's disease:

6. Take part in more social activities and do more effective things.

Marx said: "Man is the sum of all his social relations." If the elderly reduce or stop social activities because of their age, it will definitely affect their health and increase the risk of Alzheimer's disease.

Therefore, it is very important to actively encourage the elderly to participate in social activities. Socializing more helps to improve cognitive ability. Old people should go out of their homes and take part in some social activities, especially cultural and sports activities. As long as they can participate, they should actively participate, even as a bystander, which is better than being indifferent.

Cultivate a wide range of hobbies, such as painting, calligraphy, dancing, fishing, stamp collecting, etc. Try to make some achievements and deepen your interest.

Going out to eat with friends or participating in sports activities, traveling, partying, watching movies, listening to concerts, participating in various societies, participating in community voluntary activities, and visiting relatives and friends often help to improve memory and thinking ability.

In addition, American scholars' research shows that there is a clear connection between the diagnosis of cognitive impairment and people's depressive symptoms in the past year, and social withdrawal may also be an indicator to predict Alzheimer's disease.

With the enrichment of social life, there are more and more social platforms, and the user interfaces of Internet devices such as smartphones and tablets are becoming more and more friendly, and the operation difficulty is getting lower and lower. Nowadays, more and more elderly people have become loyal users of social media and online forums.

There are also many doctors who will advise elderly patients to go to social networking sites for auxiliary treatment. In the virtual world, the principle of user equality can better realize the social desire of the elderly.

For widowed single elderly people, interacting with family, friends and others on social media such as Weibo and WeChat can also help them to eliminate loneliness and release pressure.

7. Think hard and keep learning.

As the saying goes, "It's never too old to learn." Continuous learning can not only increase knowledge, but also exercise brain function and effectively prevent the occurrence of Alzheimer's disease.

Learn many languages.

Learning and mastering many languages can delay and prevent Alzheimer's disease, which is the conclusion of many studies. Most research results show that people who use two or more languages are unlikely to suffer from Alzheimer's disease.

This is because there is an area in the brain called the prefrontal cortex, which can directly affect your decision-making ability, and learning a foreign language can improve the function of this area. Early college education can increase cognitive level, and so can the result of old-age education.

Therefore, it is advisable for middle-aged and elderly people to learn one or more foreign languages in their spare time.

Cultivate a hobby

Young people and old people can cultivate their hobbies, such as dancing, playing chess, practicing calligraphy, playing musical instruments, playing crossword puzzles and playing Tai Ji Chuan. They can also read more books, news, newspapers, magazines, visit various clubs, travel, communicate with people and so on. As long as they often use their brains, it will help prevent Alzheimer's disease.

8. Maintain a good emotional and psychological state.

Depression is an important factor leading to senile dementia. Keeping a positive attitude and a good mood can prevent the occurrence of Alzheimer's disease.

Adjust mentality and position accurately.

After retirement, the social status and economic ability of the elderly may be very different from before. How to accept and adapt is a major issue for the elderly.

Therefore, the elderly should actively adapt to the changes in life and psychology, participate in social activities more, maintain their social activity ability, and avoid negative emotions such as "eating all day, having no purpose" and "being old is useless".

At the same time, the elderly should treat and handle their own affairs with a peaceful mind. Children and grandchildren have their own blessings, but more intervention and worry about their children's lives is also conducive to maintaining emotional stability.

Old people who actively seek the care of their children and relatives and friends, especially those who live alone, often feel lonely. At the same time, neglect of children may also make their parents "suffocate" Alzheimer's disease.

At this time, the elderly should actively seek the care of their children and relatives and friends, correctly express their emotional demands, or participate in group activities to improve their bad emotions through rich activities and interpersonal communication.

9. Treat the disease in time, so as not to accelerate the occurrence of Alzheimer's disease.

Clinically, cerebrovascular diseases, hypertension, diabetes, coronary heart disease, hyperlipidemia, brain trauma and other diseases are all important pathogenic factors of Alzheimer's Harmo's disease, which can directly or indirectly act on brain tissues and blood vessels, reduce blood flow, cause metabolic abnormalities, and finally lead to the occurrence of Alzheimer's Harmo's disease. Therefore, to prevent Alzheimer's disease, we must treat these diseases in time.

Cerebral Infarction

Cerebral infarction can destroy brain tissue, or cause cerebral vascular degeneration after ischemia, resulting in damage to the structure and function of blood vessels, resulting in blood supply disorder, or interacting with other risk factors can directly lead to Alzheimer's Harmo's disease, and with the increase of age, the incidence of Alzheimer's disease after cerebral infarction will also increase.

For patients with cerebral infarction, reasonable arrangement of diet, control of blood pressure at a reasonable level and scientific medication are helpful to the treatment of cerebral infarction.

encephalorrhagia

Extraparenchymal hemorrhage can cause localized or extensive brain edema by compressing surrounding tissues, which can lead to decreased cerebral blood flow; Intracerebral hemorrhage hematoma is absorbed to form cyst, which can lead to brain tissue damage at the bleeding site.

Both kinds of cerebral hemorrhage can lead to Alzheimer's disease. For patients with cerebral hemorrhage, reasonable arrangement of diet, adjustment of mood, stabilization of blood pressure and adjustment of living habits can improve symptoms and prevent the occurrence of Alzheimer's disease.

Craniocerebral trauma

After head trauma, glial cells in the brain will become extremely active and release pro-inflammatory cytokines for a long time, which is a part of brain rehabilitation mechanism, but it will lead to cognitive impairment and epilepsy, and induce Alzheimer's disease.

Therefore, for people with head trauma, they should take the initiative to seek effective treatment in time after injury, recover as soon as possible, and at the same time prevent from being injured again.

hyperlipemia

Lipid components in hyperlipidemia patients are deposited on the wall of blood vessels, which narrows and blocks blood vessels. It is not only a risk factor for vascular Alzheimer's disease, but also a vascular factor that can promote the occurrence and development of Alzheimer's disease.

For people with hyperlipidemia, we should take the initiative to control their diet, eat less or no foods rich in cholesterol and saturated fatty acids, and exercise moderately to reduce blood lipid levels.

hypertension

It is found that there is a certain relationship between Alzheimer's disease and hypertension. Increased systolic blood pressure may be the cause of Alzheimer's disease in the elderly.

Patients with hypertension should actively adjust their diet, strictly limit the amount of salt, properly supplement potassium, keep water supply, measure their blood pressure regularly, keep exercising, adjust their mood, and lower their blood pressure in many ways to prevent the occurrence of Alzheimer's disease.

arteriosclerosis

Studies have shown that the risk of cognitive decline in the elderly with high degree of arteriosclerosis is about three times that of the elderly with low degree of arteriosclerosis. Active prevention and treatment of arteriosclerosis is also one of the important measures to prevent Alzheimer's disease.

Diet is especially important for patients with arteriosclerosis. The intake of total calories, cholesterol and fat should be controlled in diet, and active activities should be taken to prevent arteriosclerosis.

diabetes

The probability of diabetic patients suffering from Alzheimer's disease is 30% ~ 65% higher than that of non-diabetic patients. Among all types of diabetes, patients with type 2 diabetes have the greatest risk of developing Alzheimer's disease. Prevention and treatment of diabetes can also prevent Alzheimer's disease.

For diabetics, keeping blood sugar stable in daily life is the key. Patients can stabilize blood sugar by controlling total calories, limiting fat and reducing the intake of high GI food. At the same time, active and effective exercise and massage methods can help patients lower their blood sugar.

heart disease

Some experts believe that any heart disease that can affect brain function can be regarded as a factor affecting the occurrence and development of Alzheimer's disease.

For patients with heart disease, measures such as limiting cholesterol intake, eating more foods rich in dietary fiber, avoiding emotional overexcitation, and paying attention to cold and warm can improve heart disease and reduce its incidence.
